The application's technical problem to be solved is to provide a kind of electro-acoustic element material strip that prevents dust, and has good vibration reduction and cushioning ability, and simple in structure, is suitable for batch production.
The application provides a kind of electro-acoustic element material strip that prevents dust, comprise that release counterdie and at least one are arranged in the dustproof unit on described release counterdie, described dustproof unit comprises the first mucigel being cascadingly set on from the bottom to top on described release counterdie, screen layer, the second mucigel and foamed cotton layer, described screen layer is net slice body structure, described foamed cotton layer, the first mucigel and the second mucigel are with described screen layer outline and match and the frame shape structure of inner side hollow, described the first mucigel, the thickness of screen layer and the second mucigel is 0.08mm ~ 0.12mm, described foamed cotton layer thickness is 0.28mm ~ 0.32mm.
Further, described screen layer adopts 180 order ~ 220 order nylon wires.
Further, described release counterdie adopts transparent release film.
Further, described release counterdie thickness is 0.08mm ~ 0.12mm.
Further, described the first mucigel and the second mucigel adopt double faced adhesive tape.
Further, described dustproof unit is set to multiple, and rectangular array is arranged on described release counterdie.
The application's beneficial effect is:
By a kind of dustproof material strip of electro-acoustic element that is provided with foam is provided, utilize the elastic performance of foam, strengthen the vibration reduction and cushioning ability of dustproof material strip, avoid electro-acoustic element get loose or damage because of frequent vibration, the useful life of effective guarantee electronic product, and simple in structure, be suitable for batch production.

Embodiment
By reference to the accompanying drawings the application is described in further detail below by embodiment.
Please refer to Fig. 1 ~ Fig. 3, the application provides a kind of electro-acoustic element material strip that prevents dust, and comprises that release counterdie 10 and at least one are arranged in the dustproof unit 20 on described release counterdie 10.As shown in Figure 1, in the application, described dustproof unit 20 is preferably set to multiple, and rectangular array is arranged on described release counterdie 10.
As shown in Figure 2, Figure 3, Figure 4, described dustproof unit 20 comprises the first mucigel 21, screen layer 22, the second mucigel 23 and the foamed cotton layer 24 that are cascadingly set on from the bottom to top on described release counterdie 10.
Described screen layer 22 is net slice body structure, plays dustproof effect, in order to prevent that extraneous dust from entering inside by the sound hole on electronic product.Described screen layer 22 in the application adopts 180 order ~ 220 order nylon wires, and thickness is set to 0.08mm ~ 0.12mm.As a kind of execution mode of the best, it is that 0.10mm, order number are 200 object nylon wires that described screen layer 22 preferably adopts thickness.
Described foamed cotton layer 24 is elastic foam, be with described screen layer 22 outlines and match and the frame shape structure of inner side hollow, the hollow space of its inner side matches in hole at the sound with the phase of electronic product, in order to the electro-acoustic element in electronic product is played to good buffering, damping effect.In the application, described foamed cotton layer 24 thickness are 0.28mm ~ 0.32mm, are preferably set to 0.30mm.
Described the first mucigel 21 and the second mucigel 23 match with described foamed cotton layer 24 shapes and size, are all with described screen layer 22 outlines and match and the frame shape structure of inner side hollow.Described the first mucigel 21 is in order to dustproof described electro-acoustic element material strip is bonding on to the sound hole place of electronic product, and described the second mucigel 23 is in order to bind described foamed cotton layer 24 and screen layer 22.In the application, described the first mucigel 21 and the second mucigel 23 all adopt double faced adhesive tape, and thickness is all set to 0.08mm ~ 0.12mm, and are preferably set to 0.10mm.
Described release counterdie 10 is used to described the first mucigel 21 belows and forms overcoats, not protect described the first mucigel 21 contaminated or damage, and described dustproof unit 20 can be taken off more easily, so that follow-up assembling.In the application, described release counterdie 10 adopts transparent release film, and thickness is 0.08mm ~ 0.12mm, is preferably set to 0.10mm.
